[cisco-voip] Outgoing Caller ID, My Router, Telco's PRI

[Jeff Ruttman]

Greetings,
 
If, when doing a "debug isdn q391" on my voice router, I see the Calling
Party presenting 10 digits to the PRI, then what else on my side of the
Caller ID equation might I alter to have those 10 digits show up on the
Called Party's phone?
 
As it stands now, the Called Party sees the number assigned to the PRI
itself and not the external mask configured on the phone, not the 10
digits I see being presented to the PRI via the debug.
 
Other points of interest:
 
We have 2 other PRIs from AT&T, and I see the same 10 digits presented
to those 2 other PRIs, and those numbers DO show up on the Called
Party's phone.
 
When I send a call out through the problem PRI and call an AT&T cell
phone, I DO SEE the proper caller id on the Called Party phone, but I do
NOT when I call, say a Sprint phone or a Verizon phone.  
 
AT&T's response to my questions on the problem PRI:
We would pass the T16OX number for caller id. It is up to the customer
to program their equipment with the DID number they want to display. I
would have him check with his vendor on his programming. I don't know
what else to suggest to him.

So anything I can try?  Push back on AT&T?

Thanks, jeff
